【発明の属する技術分野】
本発明は、家屋軒先に軒樋を施工する際に軒樋部材同士を接続するための継手、詳しくは外継手と内継手とによって軒樋部材を内外から挟み付けて軒樋部材間を接続する軒樋二重継手に関する。
【０００２】
【従来技術及び発明が解決しようとする課題】
従来のこの種の軒樋二重継手（例えば実公平５−２３６９５号や特開平４−３６８５５５号などにおいて開示されていた。）は、施工する際に接続部位を上方より目視し難く、手探りによる位置決めが容易ではないため作業に手間取るという共通の課題を抱えていた。
【０００３】
かかる課題を解決するため、特開平１０−１４０７６１号記載の発明は、図９に示すように、開口部を有する略Ｕ字状をなす軒樋部材Ａ１（Ａ２）の外周面に添う如く形成した外継手５１と、軒樋部材Ａ１（Ａ２）の内周面に添う如く形成した内継手５２とで隣接する軒樋部材Ａ１、Ａ２を挟持して接続する軒樋二重継手において、前記外継手５１の屋外側立壁５３の巾方向略中央部に位置決め突起５４を内向きに形成し、家屋側立壁５５の巾方向の略中央部に内向き係止片５６を突設する一方、前記内継手５２の屋外側立壁５７の巾方向略中央部に前記外継手５１の位置決め突起５４を係止するガイド孔５８を穿設し、施工の際には、内継手５２の家屋側立壁５９の上端を外継手５１の内向き係止片５６に係着させ、ガイド孔５８に位置決め突起５４を臨ませるようにすれば内継手５２の位置合わせと係着とをきわめて簡単に行うことができる軒樋二重継手５０を提案している。
【０００４】
ところが、この軒樋二重継手５０も含めて従来の軒樋二重継手は、軒樋部材Ａ１、Ａ２の開口部が狭い場合、内継手５２を大きく変形させなければ軒樋部材Ａ１（Ａ２）の樋内側に挿入することさえ難しく内継手５２の装着が施工上の負担となることがあった。
【０００５】
そこで本発明は、かかる課題を解決するため、軒樋部材の開口部がたとえ狭くても容易に内継手を軒樋部材内に装着することができる軒樋二重継手を提供せんとするものである。
【０００６】
【課題を解決するための手段】
かかる課題を解決するため、本発明は、底面部の前後端縁から前壁部と後壁部とを立ち上げるとともに、前記前壁部は底面部から立ち上がった立上がりの上端部を頂点としてその上側部分を樋内側へ傾倒させて、前後壁部の上部間を上方に狭窄した開口部とした断面略Ｕ字状を呈する軒樋部材の端部同士を、軒樋部材の外周面に添う如く形成された外継手と、軒樋部材の内周面に添う如く形成された内継手とを介して接続する軒樋二重継手であって、
内継手は、軒樋部材の底面部、後壁部及び前壁部の立上がりの内周面に添うように形成された下側内継手部材と、軒樋部材の前壁部の傾倒した上側部分の内周面に添うように形成された上側内継手部材とに分割し、これら上下内継手部材の分割縁にはそれぞれ上下互いに嵌合し得る係止構造を有する接合片を設けて構成され、
外継手は、軒樋部材の前壁部の外周面に添うように起立させた前立壁の内面上部に上側内継手部材の上端が係合する係止突出片を内向きに突設し、軒樋部材の後壁部の外周面に添うように立ち上げた後立壁の内面上部に下側内継手部材の後立壁の上端が係合する突起片を内向きに突設して構成されていることを特徴とする。
なお、前記の分割縁とは、例えば前立壁において上下に分割した場合には、上側内継手部材の前立壁の下端縁部と、下側内継手部材の前立壁の上端縁部とを意味する。
【０００７】
かかる構成を有する軒樋二重継手は、従来は一部材であった内継手を、前立壁において上下に分割し、かつ互いに接合可能としてあるから、たとえ軒樋部材の開口部が狭くとも内継手部材を軒樋部材の開口部から容易に軒樋部材内に挿入し装着することができ、軒樋の新規取付けや修理の作業性を大巾に改善することができる。
【０００８】
上下内継手部材の接合片内に、上下に互いに嵌合し得る係止構造を設けてあるので、互いの接合片を接合するだけで上下内継手部材を水平方向にずれないように互いに固定することができる。また、下側内継手部材の前立壁又は後立壁に摘片を設けることもできる。前立壁又は後立壁において上側内継手部材と下側内継手部材とに分割することによって、下側内継手部材を軒樋内から取り出すのに苦労する可能性があるが、上記の如く摘片を設けることによって下側内継手部材を軒樋内から容易に取り出すことができるようになり、特に修理の際の作業性を向上させることができる。
【０００９】
【発明の実施の形態】
以下、実施例に基づき本発明の実施形態について説明する。
【００１０】
本発明の一実施例に係る一例としての軒樋二重継手１は、隣接する軒樋部材Ａ１，Ａ２の端部を外継手及び内継手を介して接続するものである。ここで、軒樋部材Ａ１，Ａ２の一例について説明すると、いずれも、上方に狭窄した開口部を有する断面略Ｕ字状を呈し、底面部１０１と、底面部１０１の前端縁から外側（前方）に向かって反り返るように立ち上がり、この立上がり１０２ａの上端部を頂点１０２ｂとしてその上側部を樋内側（後方）に傾倒してなる前壁部１０２と、底面部１０１の後端縁から略垂直に立ち上がってなる後壁部１０３と、前壁部１０２の上端縁に沿って形成された外側耳部１０４と、後壁部１０３の上端縁に沿って形成された家屋側耳部１０５とを備えている。前壁部１０２と後壁部１０３の上部間の開口部は軒樋内部よりも狭窄となっている。

【００１５】
また、外継手２の内周面には、図３（Ａ）に示すように、前立壁５の上端部付近から底面４を介して後立壁６の上端部付近に至る範囲、言い換えれば軒樋部材Ａ１、Ａ２の端部と重なる範囲に亘って、その巾方向中央部分に適宜巾（例えば２２．５ｍｍ）の帯状凹部１３を設け、この帯状凹部１３の巾方向中央部に凸状リブ１４を設けている。なお、上記の係止突出片１０及び突起片１２は、この凸状リブ１４上に形成されている。
【００１６】
次に、下側内継手部材３Ａは、適宜巾（例えば８０ｍｍ）のプラスチック成形体であって、図４（Ａ）（Ｂ）に示すように、軒樋部材の底面部１０１内に嵌り得る大きさの底面１５と、軒樋部材の前壁部１０２において立上がり１０２ａの内周面に添うように底面１５の外側端縁から外側（前方）に反り返るように起立してなる前立壁１６と、この前立壁１６の上端縁から樋内側水平に屈曲してなる接合片１７と、軒樋部材の後壁部１０３に添うように底面１５の家屋側端縁部から略垂直に起立してなる後立壁１８とを備えている。
【００１７】
上記接合片１７は、前立壁１６の上端縁に沿って長尺矩形状の水平面として形成されており、接合片１７内には左右二個所に矩形状の嵌合孔１９、１９が設けられている。
【００１８】
上記後立壁１８は、外継手２の後立壁６よりも低く形成され、その上端縁は巾方向両端部から内側に向かって緩やかに上り傾斜して両肩部１８ａ、１８ａを形成し、これら両肩部１８ａ、１８ａの中央部において適宜巾に亘って上方突出して略台形状の突出部１８ｂを形成すると共に、この突出部１８ｂの上縁中央部に上記突起片１２の嵌入部１２ａと係合し得るＶ字状の切欠部２０を設けている。
そしてこの後立壁１８の内周面上部には水平方向に長尺で先端を下折してなる摘片２１を設け、後立壁１８の摘片２１の下方部位には巾方向中間部位に三角リブ板片２２が底面１５にかけて立設されている。
【００１９】
また、下側内継手部材３Ａの外周面には、前立壁１６、底面１５及び後立壁１８の全周面に亘って、すなわち軒樋部材Ａ１、Ａ２の端部と重なる範囲に亘ってその巾方向中央部分に適宜巾（例えば２２．５ｍｍ）の帯状凹部２３が設けられており、下側内継手部材３Ａの内周面には巾方向中央部分に凸状リブ２４が設けられている。なお、上記の三角リブ板片２２は、この凸状リブ２４上に形成されている。
【００２０】
次に、上側内継手部材３Ｂは、適宜巾（例えば８０ｍｍ）のプラスチック成形体であって、図５（Ａ）（Ｂ）に示すように、軒樋部材の前壁部１０２上側部分に添うように上方に向かって樋内側に傾倒してなる前立壁２５と、この前立壁２５の上端縁部から内向きやや斜め下方に張出してなる内折片２６と、前立壁２５の下端縁から樋内側水平に屈曲してなる接合片２７とを備えている。
【００２１】
内折片２６は、張出先端部を下折れし、上面には、外継手２の下向係止部１１と係合し得る断面逆Ｖ状の段差部としての上向係合受部２９を形成し、上側内継手部材３Ｂを樋内に嵌め込んでこの内折片２６を係止突出片１０の下面にあてがうと、内折片２６の上面が係止突出片１０の下面を弾性的に押し上げて下向係止部１１と上向係合受部２９とが弾性係合するように形成されている。
【００２２】
接合片２７は、上記接合片１７と重合し得る矩形状の水平面として形成され、面内には上記嵌合孔１９、１９と嵌合し得る突起部２８、２８が設けられている。
【００２３】
また、上側内継手部材３Ｂの外周面には、図５（Ａ）に示すように、内折片２６の中間部付近から前立壁２５の下端部に至る範囲、すなわち軒樋部材Ａ１、Ａ２の端部と重なる範囲に亘ってその巾方向中央部分に適宜巾（例えば２２．５ｍｍ）の帯状凹部３０が設けられ、この帯状凹部３０内の巾方向中央部には、前立壁２５の上下中間部付近を始点として内折片２６の基端部乃至中間部にかけてガイド孔としての長孔３１が形成されている。
【００２４】
次に、軒樋二重継手１を用いて軒樋部材Ａ１，Ａ２を接続する施工方法について説明する。
【００２５】
隣接する軒樋部材Ａ１及びＡ２を突合せ間隙ｄ（図８参照）を隔てて軒先に設置した後、必要に応じて内周面に接着剤を塗布した外継手２を、図６（Ａ）に示す如く、下方から拡開させながらその内周面を両軒樋部材Ａ１及びＡ２の外周面に重ねて突合せ間隙ｄを塞ぐように被着する。この際、軒樋部材Ａ１及びＡ２の外側耳部１０４は樋耳覆片７によって被覆され、家屋側耳部１０５は樋耳抱持部８内に介在して抱持される。また、係止突出片１０及び突起片１２は突合せ間隙ｄから軒樋内に突入した状態となる。
【００２６】
次いで、必要に応じて外面に接着剤を塗布するか或いは両面粘着テープを付設した下側内継手部材３Ａを、図６（Ｂ）において二点鎖線で示す如く、縦にした状態で前立壁１６側を先にして軒樋内に差し入れ、前壁部１０２の頂点１０２ｂ内面部に前立壁１６の上端部を当接し、続いて後立壁１８側を下方に押し込むと同時に後立壁１８を後方に押し込んで、突起片１２（嵌入部１２ａ）の下側に切欠部２０を係合させる。これにより、下側内継手部材３Ａを軒樋内に嵌め込むことができ、前立壁１６、底面１５及び後立壁１８のそれぞれを軒樋部材Ａ１及びＡ２の前壁部１０２、底面部１０１及び後壁部１０３に添って重合した状態とすることができる。
【００２７】
そして次に、必要に応じて外面に接着剤を塗布するか或いは両面粘着テープを付設した上側内継手部材３Ｂを、図６（Ｃ）において二点鎖線で示す如く、接合片２７側から先に軒樋内に差し入れ、外継手２の係止突出片１０と長孔３１とが嵌合する位置を探し、係止突出片１０と長孔３１とを嵌合させた状態を維持するように上側内継手部材３Ｂを前壁部１０２に沿って下方に移動させて接合片２７を下側内継手部材３Ａの接合片１７上に重ねる。すると、突起部２８、２８と嵌合孔１９、１９とを嵌合させることができる。続いて、内折片２６を押し下げつつ上側内継手部材３Ｂを外側（前方）すなわち前壁部１０２側に押し込んで内折片２６を下方から解放すれば、当該内折片２６の弾性反力を伴って上向係合受部２９と下向係止部１１とが係合し、上側内継手部材３Ｂを軒樋内に固定することができ、同時に軒樋二重継手１の施工を完成することができる。
【００２８】
かかる軒樋二重継手１の施工において、従来は一部材であった内継手３を前立壁において上下内継手部材３Ａ、３Ｂに分割したことにより、上下内継手部材３Ａ、３Ｂのいずれも軒樋内に容易に差し入れることができる。そればかりか、無理に変形させなくても容易に嵌着、言い換えれば軒樋部材内の所定個所に所定の姿勢で固定することができる。下側内継手部材３Ａについて言えば、軒樋内に差し入れて下方に押し込みつつ切欠部２０を突起片１２（嵌入部１２ａ）に係合させるように嵌め込むだけで正しい位置に正しい姿勢で装着することができ、上側内継手部材３Ｂについては、長孔３１をガイド孔としてこの長孔３１と係止突出片１０との嵌合に沿って移動させ、続いて内折片２６の上向係合受部２９を外継手２の下向係止部１１に係合させるように嵌め込むだけで正しい位置に正しい姿勢で装着することができる。
【００２９】
しかも、上側内継手部材３Ｂを嵌め込んで上向係合受部２９と下向係止部１１とを係合させることによって、外継手２、下側内継手部材３Ａ及び上側内継手部材３Ｂを水平方向にも上下方向にも固定することができ、同時に軒樋部材Ａ１、Ａ２を挟止することができる。
すなわち、軒樋二重継手１で軒樋部材Ａ１、Ａ２を接続した状態においては、図２、図７及び図８に示すように、外継手２の突起片１２（嵌入部１２ａ）と下側内継手部材３Ａの切欠部２０との係合によって外継手２と下側内継手部材３Ａとは上下方向には勿論、巾方向にも互いに固定される。また、この下側内継手部材３Ａと上側内継手部材３Ｂとは、上下接合片１７、２７の突起部２８、２８と嵌合孔１９、１９との嵌合によって少なくとも巾方向に互いに固定され、上側内継手部材３Ｂと外継手２とは、上向係合受部２９と下向係止部１１との係合によって少なくとも上下方向に固定され、これにより、外継手２、下側内継手部材３Ａ及び上側内継手部材３Ｂは、互いに水平方向にも上下方向にも固定される。
【００３０】
また、軒樋二重継手１は、外継手２の内周面に帯状凹部１３を設け、上下内継手部材３Ａ、３Ｂの外周面に帯状凹部２３、３０を設けることによって、軒樋部材Ａ１，Ａ２の端部に発生したバリをこれら帯状凹部内に収納することができるから、軒樋部材Ａ１，Ａ２と外継手２の内周面との間、及び軒樋部材Ａ１，Ａ２と上下内継手部材３Ａ、３Ｂの外周面との間にバリが入り込んで隙間を生じることがなく、これらを互いに密着状態に接合させることができ、継手部からの漏水防止を無くすことができる。
【００３１】
さらにまた、軒樋二重継手１においては、摘片２１を摘まんで下側内継手部材３Ａを軒樋内から容易に取り出すことができるから、修理時などにおいて特に便利になっている。

The upper inner joint member formed so as to follow the inner peripheral surface of the upper and lower inner joint members is divided into the upper and lower inner joint members, each of which is provided with a joining piece having a locking structure that can be fitted to each other,
The outer joint protrudes inwardly with a locking protruding piece that engages with the upper end of the upper inner joint member on the inner surface of the front wall that is erected so as to follow the outer peripheral surface of the front wall portion of the eaves member. A projecting piece is formed to project inwardly on the inner surface of the rear standing wall that is raised so as to follow the outer peripheral surface of the rear wall portion of the flange member, and to engage the upper end of the rear inner wall of the lower inner joint member. It is characterized by that.
In addition, the said division | segmentation edge means the lower end edge part of the front wall of an upper inner joint member, and the upper end edge part of the front wall of a lower inner joint member, when dividing | segmenting up and down, for example in a front wall. .
[0007]
In the eaves double joint having such a configuration, the inner joint that has been a single member in the past is divided vertically into the front wall and can be joined to each other, so even if the opening of the eaves member is narrow, the inner joint The member can be easily inserted into and attached to the eaves member from the opening of the eaves member, and the workability of new attachment and repair of the eaves can be greatly improved.
[0008]
A locking structure that can be fitted to each other vertically is provided in the joint pieces of the upper and lower inner joint members, so that the upper and lower inner joint members are fixed to each other so as not to be displaced in the horizontal direction only by joining the joint pieces. be able to. Moreover, a handle can also be provided in the front wall or rear wall of the lower inner joint member. It may be difficult to take out the lower inner joint member from the eaves by dividing the upper inner joint member and the lower inner joint member in the front wall or the rear wall. By providing, the lower inner joint member can be easily taken out from the eaves, and the workability especially at the time of repair can be improved.
[0009]
